From: Arnd Bergmann <arnd@xxxxxxxx> [ Upstream commit bac717171971176b78c72d15a8b6961764ab197f ] dtc points out that the interrupts for some devices are not parsable: picoxcell-pc3x2.dtsi:45.19-49.5: Warning (interrupts_property): /paxi/gem@30000: Missing interrupt-parent picoxcell-pc3x2.dtsi:51.21-55.5: Warning (interrupts_property): /paxi/dmac@40000: Missing interrupt-parent picoxcell-pc3x2.dtsi:57.21-61.5: Warning (interrupts_property): /paxi/dmac@50000: Missing interrupt-parent picoxcell-pc3x2.dtsi:233.21-237.5: Warning (interrupts_property): /rwid-axi/axi2pico@c0000000: Missing interrupt-parent There are two VIC instances, so it's not clear which one needs to be used. I found the BSP sources that reference VIC0, so use that: https://github.com/r1mikey/meta-picoxcell/blob/master/recipes-kernel/linux/linux-picochip-3.0/0001-picoxcell-support-for-Picochip-picoXcell-SoC.patch Acked-by: Jamie Iles <jamie@xxxxxxxxxxxxx> Link: https://lore.kernel.org/r/20201230152010.3914962-1-arnd@xxxxxxxxxx' Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- arch/arm/boot/dts/picoxcell-pc3x2.dtsi | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/arm/boot/dts/picoxcell-pc3x2.dtsi b/arch/arm/boot/dts/picoxcell-pc3x2.dtsi index 533919e96eaee..f22a6b4363177 100644 --- a/arch/arm/boot/dts/picoxcell-pc3x2.dtsi +++ b/arch/arm/boot/dts/picoxcell-pc3x2.dtsi @@ -54,18 +54,21 @@ emac: gem@30000 { compatible = "cadence,gem"; reg = <0x30000 0x10000>; + interrupt-parent = <&vic0>; interrupts = <31>; }; dmac1: dmac@40000 { compatible = "snps,dw-dmac"; reg = <0x40000 0x10000>; + interrupt-parent = <&vic0>; interrupts = <25>; }; dmac2: dmac@50000 { compatible = "snps,dw-dmac"; reg = <0x50000 0x10000>; + interrupt-parent = <&vic0>; interrupts = <26>; }; @@ -243,6 +246,7 @@ axi2pico@c0000000 { compatible = "picochip,axi2pico-pc3x2"; reg = <0xc0000000 0x10000>; + interrupt-parent = <&vic0>; interrupts = <13 14 15 16 17 18 19 20 21>; }; }; -- 2.27.0
